Their life was full of experiences shared with him. He has his reserve--his secret; yet, in another sense, he gives himself to them without reserve; there is prodigality of self-impartation in his dealings with them. He lets them have everything they can take. He becomes theirs in a great intimacy, he gives himself to them. Why? Because he believes, as he put it, in seed. Socrates saw that the teacher's real work, his only work, is to implant the idea, like a seed; an idea, like a seed, will look after itself. A king builds a temple or a palace. The seed of a banyan drifts into a crack, and grows without asking anyone's leave; there is life in it. In the end the building comes down, but for what the banyan holds up. The leaven in the meal is the most powerful thing there. There is very little of it, but that does not matter; it is alive (Matt. 13:33). Life is a very little thing but it is the only thing that counts. That is why the farmer can sow his fields and sleep at nights without thinking of them; and the crop grows in spite of his sleeping, and he knows it (Mark 4:26). That is why Jesus believes so thoroughly in his men, and in his message; God has made the one for the other, and there is no fear of mischance. Look at his method of teaching. People "marvelled at his words of charm" (Luke 4:22)--"hung about him to hear him" (Luke 19:48). He said that the word is the overflow of the heart. "Out of the abundance of the heart the mouth speaketh" (Matt. 12:34; Luke 6:45). What a heart, then, his words reveal! How easy and straightforward his language is! To-day we all use abstract nouns to convey our meaning; we cannot do without words ending in -ality and -anon. But there is no recorded saying of Jesus where he uses even "personality." He does not use abstract nouns. He sticks to plain words. When he speaks about God he does not say "the Great First Cause," or "Providence," or any other vague abstract. Still less does he use an adverb from the abstract, like "providentially." He says, "your heavenly Father." He does not talk of "humanity"; he says, "your brethren." He has no jargon, no technical terms, no scholastic vocabulary. He urges men not to over-study language; their speech must be simple, the natural, spontaneous overflow of the heart.[20] Jesus told his disciples not to think out beforehand what they would say when on trial (Mark 13:11)--it would be "given" to them. He was perfectly right; and when Christians obeyed him, they always spoke much better than when they thought out speeches beforehand. They said much less for one thing, and they said it much better. Take the case of the martyr--an early and historical one--whose two speeches were during her trial "Christiana sum" and, on her condemnation, "Deo gratias".
